Under 35 U.S.C. 119, this application claims the benefit and right of priority of Chinese Patent Application No. 201811015495.X, filed on 31 Aug. 2018.

BACKGROUND Field

This disclosure is generally related to the technical field of artificial intelligence and machine learning. More specifically, this disclosure is related to a method and system for facilitating detection and identification of vehicle parts.

Related Art

In conventional vehicle damage assessment approaches, a vehicle insurance company can send a professional (such as an insurance adjuster) to conduct a manual on-site survey and determine a repair plan for a damaged vehicle. After the professional captures images of the damaged vehicle, these “captured images” can be compared against similar images in a library or database of images. The library can include images of damaged vehicle parts, which were previously captured from other images of other damaged vehicles (“library images”). In a conventional vehicle damage assessment approach, a system can determine the damage assessment result of the damaged vehicle based on the comparison of the captured images with the library images.

However, conducting a manual survey and determining a repair plan based on the comparison of the captured images against library images can result in a long processing time, and can incur a significant cost in manpower and training of professionals. Current approaches can use image-based artificial intelligence and machine learning in vehicle damages assessment approaches that may reduce both processing time and labor costs. For example, these approaches can enable automatic identification of damaged parts and the degree of the damage based on on-site pictures of the vehicle taken by users. In addition, the on-site pictures of the vehicle can be used by computer-vision image identification technology with artificial intelligence to provide a repair solution. Therefore, by automating the survey and damage assessment approaches, the labor costs incurred by a vehicle insurance company can be reduced and the vehicle insurance claiming experience of a user can be improved.

While using the automated survey and damage assessment approach can result in some benefits, some challenges still remain in providing accurate identification of vehicle parts and the degree of damage of those parts.

SUMMARY

One embodiment facilitates detection and identification of vehicle parts. During operation, the system stores a captured image of a vehicle, wherein the captured image includes a plurality of parts of the vehicle. The system detects a first area of the captured image in which a first part of the vehicle is located. The system identifies, from a plurality of predetermined classes, a class corresponding to the first part in the detected first area, wherein the class indicates a location of the first part in relation to the vehicle. The system generates a result which indicates a list including an insurance claim item and corresponding damages based on the first area, the first part, and the class corresponding to the first part.

In some embodiments, the system detects the first area by performing the following operations. The system divides the captured image into a grid of squares. The system maps, for a respective square, the respective square to a first number of target areas, wherein a respective target area comprises a bounding box associated with at least the respective square. The system determines, for the respective target area, a confidence coefficient which indicates a likelihood that the respective target area corresponds to a first predetermined class. The system determines, for the respective square, a probability which indicates a likelihood that the respective square corresponds to each of the predetermined classes. The system selects, based on the confidence coefficient and the probability, a second area as the first area in which the first part of the vehicle is located, wherein the second area is selected from all target areas mapped to each of the squares.

In some embodiments, a second number of squares of the grid in a horizontal direction are the same as a second number of squares of the grid in a vertical direction, and the first number and the second number are positive integers.

In some embodiments, prior to storing the captured image of the vehicle, the system acquires a plurality of unsorted images of the vehicle, wherein the unsorted images are captured directly by a user of the vehicle. The system sorts the unsorted images by removing images which are irrelevant or abnormal to obtain a set of captured images which include the captured image.

In some embodiments, detecting the first area is based on a first algorithm. Prior to detecting the first area of the captured image, the system trains the first algorithm based on: images with pre-marked areas indicating final locations for multiple parts of the vehicle; and a plurality of sample images of a predetermined class corresponding to a respective part of the vehicle.

In some embodiments, detecting the first area is further based on the trained first algorithm.

In some embodiments, the first algorithm is a You Only Look Once v2 (yolov2) algorithm, and the first algorithm further comprises a model based on a neural network.

In some embodiments, a class includes one or more of: a left front door; a right front door; a left rear door; a right rear door; a front bumper; a rear bumper; a left front wheel fender; a right front wheel fender; a left rear wheel fender; a right rear wheel fender; a left front tire; a right front tire; a left rear tire; a right rear tire; a lower grille; a middle grille; a left headlight; a right headlight; a left brake light; a right brake light; a left front emergency light; a right front emergency light; a left rear emergency light; a right rear emergency light; a number plate; a front engine hood; and a trunk.

DETAILED DESCRIPTION

The following description is presented to enable any person skilled in the art to make and use the embodiments, and is provided in the context of a particular application and its requirements. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present disclosure. Thus, the embodiments described herein are not limited to the embodiments shown, but are to be accorded the widest scope consistent with the principles and features disclosed herein.

Overview

The embodiments described herein address the challenges of accurately detecting and identifying vehicle parts by: detecting, in a captured image of a vehicle, an area in which a vehicle part is located; identifying a class corresponding to the vehicle part; and displaying an annotated image which indicates the detected area, the vehicle part, and the corresponding class. The class can indicate a location of the first part in relation to the vehicle.

As described above, sending a professional to capture on-site images of a damaged vehicle and to determine a repair plan may involve subsequently comparing the captured images with “library images.” The damage assessment result can be based on the comparison of the captured images with the library images. However, conducting a manual survey and determining a repair plan based on the comparison of the captured images against library images can result in a long processing time, and can incur a significant cost in manpower and training of professionals. Current approaches can use image-based artificial intelligence and machine learning in vehicle damages assessment approaches that may reduce both processing time and labor costs. For example, these approaches can enable automatic identification of damaged parts and the degree of the damage based on on-site pictures of the vehicle taken by users. In addition, the on-site pictures of the vehicle can be used by computer-vision image identification technology with artificial intelligence to provide a repair solution. Therefore, by automating the survey and damage assessment approaches, the labor costs incurred by a vehicle insurance company can be reduced and the vehicle insurance claiming experience of a user can be improved.

Another challenge in automated survey and damage assessment approaches is that the system must identify not only the damaged parts, but the location of the damaged parts in relation to the vehicle. That is, given a “door” part of a vehicle, the cost of repairing a “left front door” may be different from the cost of repairing a “right rear door.” Thus, while using the automated survey and damage assessment approach can result in some benefits, some challenges still remain in providing accurate identification of vehicle parts and the degree of damage of those parts.

The embodiments described herein address these challenges by providing a system which can be trained using pre-marked images (which can include bounding boxes around a specific vehicle part and a corresponding class for the specific vehicle part) and sample images of vehicle parts corresponding to certain classes. Given a user-captured image of a vehicle (e.g., as taken at an accident site by a user in physical proximity to the vehicle), the system can detect an area of the captured image in which a first vehicle part is located. The system can be based on a trained yolov2 algorithm, and can identify a class corresponding to the vehicle part in the detected area, where the class indicates a location of the vehicle part in relation to the vehicle (e.g., “right front wheel” rather than simply “wheel”). Upon identifying the corresponding class for a given vehicle part in a detected area of the captured image, the system can display an annotated image which indicates the detected area, the vehicle part, and the corresponding class, for a plurality of parts of the vehicle.

Furthermore, based on the annotated image and other annotated images of other vehicle parts, the system can generate a report which indicates a degree of damage to a specific vehicle part, and, generally, a degree of damage to the vehicle. This can result in an improved damage assessment approach which reduces the labor costs incurred by a vehicle insurance company and also increases the efficiency of the user's experience in reporting the damages, e.g., in a claims report or subsequent to an accident. Moreover, the embodiments described herein can provide an improved and more accurate method of damage assessment by clearly labeling (annotating) the captured image with bounding boxes which display the detected area, the vehicle part, and the corresponding class. This can result in a more efficient and accurate understanding of the degree of damages, which can result in an improved vehicle loss assessment report.

Exemplary Environment for Facilitating Detection and Identification of Vehicle Parts

FIG. 1 illustrates an exemplary environment 100 for facilitating detection and identification of vehicle parts, in accordance with an embodiment of the present application. Environment 100 can include: a vehicle 120; a user 102 associated with a computing device 104; a server 106; a server 108; and a server 110 associated with a display 112 and a user 114. Computing device 104 and servers 106-108 can communicate with each other over a network 101.

Computing device 104 can include a camera which can capture images of, e.g., a vehicle 120 which is a damaged vehicle on-site after an accident. During operation, computing device 104 can send a captured image 122 (of vehicle 120) to server 108 as a captured image 124. Server 108 can obtain and store a plurality of images (function 130). The obtained and stored images can include captured image 124 and training data 128, as described below. Server 108 can detect and identify a plurality of vehicle parts of vehicle 120 based on the captured image 124 and training data 128 (function 132). Server 108 can also generate a report (function 134). The generated report can indicate a degree of damage to the detected and identified vehicle parts, and can also provide a repair plan for the damaged vehicle parts. The generated report can include, e.g., information about the detected and identified parts and a repair plan for fixing those parts (i.e., parts information 136 and a repair plan 138).

Server 108 can send parts information 136 and repair plan 138 back to computing device 104 (as parts information 148 and a repair plan 150), which can be used to display various items and images on a display screen of computing device 104, e.g., based on specific application scenarios. For example, computing device 104 can display, on its respective display screen, an annotated image 152 (shown in FIG. 1 as displayed on display 112) based on parts information 148 and repair plan 150.

In addition, server 110 can send a request 140 to server 108. Request 140 can be, e.g.: a request for all repair plans generated within a predetermined period of time; a request for a repair plan specific to a particular user or time; a request for information about parts relating to a particular vehicle or user or captured image. Server 108 can receive request 140 as a request 142, and, subsequent to performing functions 130, 132, and 134 (as described above), server 108 can send parts information 136 and repair plan 138 back to server 110 (as parts information 144 and a repair plan 146). Upon receiving parts info 144 and repair plan 146, server 110 can display, on its display 112, an annotated image 152 of previously captured image 122. Annotated image 152 can indicate:

a first area of captured image 122 in which a first part of the vehicle is located; the first part of the vehicle; and the class corresponding to the first part of the vehicle, where the class can indicate the specific or final location of the first part in relation to the vehicle. Exemplary annotated images are described below in relation to FIGS. 5A and 5B. Computing device 104 can also display, on its respective display screen, annotated image 152 based on parts information 148 and repair plan 150.

Server 110 may also receive parts info 144 and repair plan 146 automatically, e.g., at a predetermined time or time interval and/or without first sending request 140. User 114 can view this information on display 112, and can use the information to conduct further actions, e.g., based on the received information being integrated into a damage assessment application or program (not shown) running on server 108 or 110.

Furthermore, prior to computing device 104 sending captured image 122 to server 108, server 106 can send training data 126 to server 108.

Training data 126 can include images with pre-marked or pre-labeled areas indicating final locations for multiple parts of a vehicle. Training data 126 can also include a plurality of sample images of a predetermined class corresponding to a respective part of a vehicle. Server 108 can receive training data 126 (as training data 128), and use training data 128 to train a neural model based on an algorithm, such as the You Only Look Once v2 (“yolov2”) algorithm, which can result in a trained algorithm (function 129). Server 108 can subsequently use the trained algorithm to detect and identify vehicle parts on incoming captured images (e.g., captured image 122 of vehicle 120, as received from computing device 104 and as taken by user 102 using computing device 104).

FIG. 2 illustrates an exemplary environment 200 for facilitating detection and identification of vehicle parts, in accordance with an embodiment of the present application. In environment 200, server 108 can receive captured image 124 and training data 128, and can perform the functions described above in environment 100. Server 108 can include: an image sorting module 210; a parts detecting and identifying module 220; and a vehicle loss assessing module 230. Upon receiving a plurality of captured images which have not yet been sorted (“unsorted images”), image sorting module 210 can sort the unsorted images by removing images which are irrelevant or abnormal to obtain a set of captured sorted images 242 which include captured image 124. An irrelevant image can include an image which does not show any vehicle parts that can be identified, or which depicts only or mostly a background associated with the vehicle. An abnormal image can include an image which includes multiple vehicles, indistinguishable vehicle parts, blurry portions, or other features which render the image out of the ordinary or not useful.

Image sorting module 210 can send both sorted images 242 and training data 244 (i.e., training data 128) to parts detecting and identifying module 220, which can include the following sub-modules: an image acquiring module 222; a parts detecting module 224; and a model training module 226. Image acquiring module 222 can perform functions similar to function 130 of FIG. 1; parts detecting module 224 can perform functions similar to function 132 of FIG. 1; and model training module 226 can perform functions similar to function 129 of FIG. 1. After sub-modules 222, 224, and 226 of module 220 have performed their functions, module 220 can send parts info 246 to a vehicle loss assessing module 230. Parts info 246 can allow vehicle loss assessing module 230 to display an annotated image indicating a detected area of a vehicle part, the vehicle part, and the corresponding class for the vehicle part. Vehicle loss assessing module 230 can perform functions similar to function 134 of FIG. 1. In addition to generating a report (as in function 134), vehicle loss assessing module can also generate a repair plan 248, and server 108 can subsequently display the generated repair plan 248 on a display screen.

FIG. 3 presents a flowchart 300 illustrating an exemplary method for facilitating detection and identification of vehicle parts, in accordance with an embodiment of the present application. During operation, the system stores a captured image of a vehicle, wherein the captured image includes a plurality of parts of the vehicle (operation 302). The system detects a first area of the captured image in which a first part of the vehicle is located (operation 304). The system identifies, from a plurality of predetermined classes, a class corresponding to the first part in the detected first area, wherein the class indicates a location of the first part in relation to the vehicle (operation 306). The system generates a result which indicates a list including an insurance claim item and corresponding damages based on the first area, the first part, and the class corresponding to the first part (operation 308). The system can store the generated result, and use the generated result to produce, e.g., reports. In some embodiments, the system can display, on a display screen of a computing device, an annotated image of the captured image, wherein the annotated image indicates the first area, the first part, and the class corresponding to the first part. The system can generate, based on the annotated image, a report which indicates a degree of damage to the first part. Note that the annotated image is not always necessary for generating the result or identifying the corresponding class.

Exemplary Method for Facilitating Detection and Identification of Vehicle Parts, Including Training a Neural Model

FIG. 4A presents a flowchart 400 illustrating an exemplary method for facilitating detection and identification of vehicle parts, in accordance with an embodiment of the present application. During operation, the system trains a first algorithm based on: images with pre-marked areas indicating final locations for multiple parts of the vehicle; and a plurality of sample images of a predetermined class corresponding to a respective part of the vehicle (operation 402). A pre-marked area can include annotations of an area in which a first vehicle part is located, the first vehicle part, and a class corresponding to the first vehicle part.

The system acquires a plurality of unsorted images of the vehicle, wherein the unsorted images are captured directly by a user of the vehicle (operation 404). The system sorts the unsorted images by removing images which are irrelevant or abnormal to obtain a set of captured images which include the captured image (operation 406). The system acquires and stores a captured image of a vehicle, wherein the captured image includes a plurality of parts of the vehicle (operation 408).

The system detects, based on the first algorithm, a first area of the captured image in which a first part of the vehicle is located (operation 410). The system divides the captured images into a grid of squares (operation 412). The system maps, for a respective square, the respective square to a first number of target areas, wherein a respective target area comprises a bounding box associated with at least the respective square (operation 414). The operation continues at Label A of FIG. 4B.

FIG. 4B presents a flowchart 420 illustrating an exemplary method for facilitating detection and identification of vehicle parts, in accordance with an embodiment of the present application. The system determines, for the respective target area, a confidence coefficient which indicates a likelihood that the respective target area corresponds to a first predetermined class (operation 422). The system determines, for the respective square, a probability which indicates a likelihood that the respective square corresponds to each of the predetermined classes (operation 424). The system selects, based on the confidence coefficient and the probability, a second area as the first area in which the first part of the vehicle is located, wherein the second area is selected from all target areas mapped to each of the squares (operation 426).

The system identifies, from a plurality of predetermined classes, a class corresponding to the first part in the detected first area (operation 428). The class indicates a location of the first part in relation to the vehicle. The system generates a result which indicates a list including an insurance claim item and corresponding damages based on the first area, the first part, and the class corresponding to the first part (operation 430). In some embodiments, the system can display, on a display screen of a computing device, an annotated image of the captured image, wherein the annotated image indicates the first area, the first part, and the class corresponding to the first part. The system can generate, based on the annotated image, a report which indicates a degree of damage to the first part. As described above, the annotated image is not always necessary for generating the result or identifying the corresponding class.

Annotated image 500 can include, for a plurality of vehicle parts: a first area of the captured image in which a first part of the vehicle is located; the first vehicle part; and a class corresponding to the first vehicle part. In annotated image 500, the system has detected and identified the following vehicle parts: a front engine hood; a right front wheel fender; a right front wheel; a front bumper; a right headlight; a lower grille; a middle grille; a vehicle logo; and a front license plate.

In annotated image 500, for the vehicle part which is the right front wheel, the system can display the following annotations: a detected area 504 in which the right front wheel is located; a part 506 which is the vehicle part which is detected and identified; and a class (indicating location) 502 for the right front wheel. Class 502 is “Right front wheel,” and indicates the location of the wheel in relation to the vehicle (i.e., “right” and “front”). Furthermore, in annotated image 500, for the vehicle part which is the front license plate, the system can display the following annotations: a detected area 514 in which the front license plate is located; a part 516 which is the vehicle part which is detected and identified; and a class (indicating location) 512 for the front license plate. Class 512 is “Front license plate,” and indicates the location of the license plate in relation to the vehicle (i.e., “front”).

FIG. 5B illustrates an exemplary annotated image 550 of a captured image, in accordance with an embodiment of the present application.

In annotated image 550, for the vehicle part which is the right front wheel, the system can display the following annotations: a detected area 554 in which the right front wheel is located; a part 556 which is the vehicle part which is detected and identified; and a class (indicating location) 552 for the right front wheel. Class 552 is “Right front wheel,” and indicates the location of the wheel in relation to the vehicle (i.e., “right” and “front”). Furthermore, in annotated image 550, for the vehicle part which is the front license plate, the system can display the following annotations: a detected area 564 in which the front license plate is located; a part 566 which is the vehicle part which is detected and identified; and a class (indicating location) 562 for the front license plate. Class 562 is “Front license plate,” and indicates the location of the license plate in relation to the vehicle (i.e., “front”).

Each vehicle part identified in annotated images 500 and 550 can be generally referred to as a part (e.g., a wheel, a headlight, a bumper, a grille, a fender, a license plate, etc.), and can correspond to a specific class which indicates the location of the part in relation to the vehicle (e.g., right front wheel, right headlight, front bumper, middle grille, right front wheel fender, and front license plate, etc.). Annotated images 500 and 550 can therefore include: a detected area indicated by a bounding box, where the detected area includes a specific vehicle part; the specific vehicle part itself; and the class corresponding to the specific vehicle part, where the class indicates the location of the specific vehicle part in relation to the vehicle.
